ATTORNEY Patented June 27, 1933 YuNITEnsrATes rarest emce GUY'MPFRENOH, on BENFREW, ONTARIO, onnnps DOOR- OPERATING DIEANS Application filed December 22, 1330, Serial No. 503,992. -Renewed October 2,1981.

This invention relates to door opening 7 mechanism and has for its principal object the provision of means whereby double doors, such as garage doors, may beswung simultaneously to open or closed position. I

Another object is the provision of means whereby the operating mechanism may be actuated from a distance. i

Another object is the provision of means whereby the doors will be fixedly retained in either open or closed position. v

With these and other objects in view as will appear as thedescription proceeds, the invention consists of the novel construction, 15 combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming a part of the present application, in which:

The figure is a topplan view of thepreferre'd embodiment of my invention. p

Like numerals of reference designate corresponding parts throughout the different views.

1 is a guide bar mounted for reciprocal and lateral movement in guide brackets 2 and 3,

which guide brackets are supported from the ceiling of a garage or suitable platform, The forward end of the guide bar 1 is notched at one corner as at 4. Adjacent the rear end of the guide bar 1 is a notch 5, the purpose of which will presently be disclosed. Connected to the forward end of the guide bar 1 is a flexible pull member 6, which pull member extends forwardly at an angle and is trained around the pulley 7, around the pulley 8 and forwardly through an opening 9 in the front wall of the garage. The flexible member 6 may be extended a predetermined distance in advance of the front of the garage and provided with a suitable ring or handle.

Connected to the rear end of the guide bar 1 is a flexible pull member 10, which is trained over the pulley 11, pulley 12 and extended forwardly through the opening 9 to a position adjacent the free end of the fiexible'member 6. The free end of the member may be provided with a suitable ring or handle.

14 and 15 are connecting rods pivotally connected at one end by means of the bolt i and 20,the fiexiihlemember 6 willbe F 16 to the guide-bar 1, the opposite ends of the connecting rods 14 and 15 are pivotally connected, by means of the bearing brackets 17 and 18, to the doors 19'and 20 respectively. .Secured, preferably, to the bracket 3 is a leaf-spring 21, the free end of which compressively contacts with the side of the guide bar 1. Connected preferably to theguide bracket 2 is a leaf-spring 22, the free end of which compressivelycontacts with the side of the guide bar 1. 1 I I l/Yhen the doors are in closedposition, the guide bar is in-position as shown in fulllines in the drawing, a portion of the bracket 3 .registeringin the notch 4 of the guide bar 05 1 and the forwardend of the guide bar 1 is restrained from lateral movement bymeans of the leaf-spring 21. In this manner the doors 19 and 20 are retained in closed position through the medium of the bearing brackets 17 and 18, connecting rods 14: and 15,

bolt 16 and guide bar 1.

. IVhen it is desirous ofropening the doors pulled in the direction of the arrow and, as the samewis pulled, the forward end of the guide bar 1 will be pulled sidewise against the compression of the leaf-spring 21 until the guide bracket 3 is free of the notch 41. The 7 guide bar 1 will now be pulled forwardly until the notch 5 at the rear end thereof registers with the guide bracket'2. As the notch 5 registers opposite the guide bracket 2, the leafspring 22 will move the rear end of the guide bar 1 sidewise to engage the side of the bracket 2 in the notch 5 and will retain the guide bar 1 in position as shown in dotted lines As the guide bar 1 is moved forward- 1y, as just hereinbefore described, the doors 19 and 20 will be moved from the position as shown in full lines 'to the open position as shown in dotted lines through the medium of the bolt 16, connecting rods 14 and 15 and bearing brackets 17 and 18, and will be retained in fixed open position through the engagement of the side of the bracket 2 in the notch 5. When it is desirous of closing the doors 19 and 20, the flexible pull member 10 will be pulled and as-thesame is pulled, the rear end of the guide bar 1 will be moved '10 sidewise to disengage the bracket 2 from the notch 5. The guide bar 1 will now be pulled rearwardly until'the notch 4 registers with the side of the bracket 3 when the leaf-spring 21 will cause the forward end of the guide bar 1 to move sidewise to engage the-side of the bracket 3 in the notch 4. As the guide bar thus moves rearwardly, the doors 19 and 20 will be moved from the position as shown in dotted lines to the closed position as shown in full lines, through the medium of the bolt 16, connecting rods 14 and 15 and I bearing brackets 17 and 18. The respective connections between the connecting rods 14 and 15 and the bearing'brackets 17 and 18 and the guide bar 1 may be sufliciently loose to allow the side play ofthe guide bar 1 during opening and closingoperations.

The foregoing specifications and annexed drawing disclose the preferred embodiment of my'invention; but it is to'be understood that minorchangw may be resorted to in the commercial adaptation of my inventioniwithout departing from the scope of the invention ashereinafter claimed.
